Wow. This scent is an intense hit of burning garbage and food. Yes it's not much of a stretch to smell the churros. Fried stuff.. sugar.. dough.. overly ripe fruit. And like a pall over these confections a smoky burnt smell, "should they be burning that?"
Dia de Los Muertos is the olfactory equivalent of Found Art. The burning garbage smell pervades parts of Mexico and for the long time returnee it's part of the rush that says you are back. It's awful, it's refuse, it's true to a time and place and to experience it in a perfume oil celebrating the Mexican Day of the Dead is a wonderful thing.
Traditional foods used for Dia de los Muertos.
"..dry, crackling leaves, the incense smoke of altars honoring Death and the Dead, funeral bouquets, the candies, chocolates, foods and tobacco of the ofrenda, amaranth, sweet cactus blossom and desert cereus."
